I picked up a harness today for my brake controller.

In an earlier post someone stated I needed to use the brown wire for the brake switch.

I ordered the 2003 harness, it has 5 wires on it, came with a 40 amp fuse for the underhood fuse bax and a 7-wire to 4-wire adapter. Not bad for $25 from the dealer.

DK BLUE -- Trailer Brake controller switched output

RED -- Fused Trailer Brake Controller Battery feed

BLK -- Brake Controller Ground

LT BLU -- Vehical Stop lamp switch to brake controller

BRN -- Brake controller illumination

Do I have the 2003 harness? I think I do. If so I guess I do NOT need to use the brown wire for the brake switch, right?

I just want to be sure not to blow anything up.

 

Don't know, but let's TTT for ya. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

dark blue--brake out
red--fuse bat+
lt blue--brake signal
black--brake ground
brown--illumination
i did not hook up the brown wire on mine 2002 silverado.

Thanks for the input guys! I wired it all up and everything work fine. I just did not use the brown wire( controller illumination).

Thanks again!
